Would prefer MS did their own browser
Yes they caused chaos in the past with standards brealkng IE only stuff... and I do not wnat a repeat of that scenario (befre anyone puts the boot in on taht point)
.. Similarly a browser should not be an integral part of the OS as were so many IE components for so long, it should just be another application.
I would like plenty of choice in the browser arena though & MS really ought to have kept their flagship browser going.
The browser choices are getting too chromium dependent for my liking - not happy with single point of failure / common attack vector, would like a more mixed browser "ecosystem": There will always be browser bugs / exploits, but zero day browser bugs become mega when a huge percentage of people are using esentially the same browser with a few customized tweaks on top.
